Working principle of laboratory mixer

When the internal mixer is working, the two rotors rotate relative to each other, clamping the material from the feeding port and bringing it into the roller gap under the compression and shear of the rotor. After passing through the roller gap, it hits the lower top bolt edge and is divided into two parts, which respectively travel along the gap between the front and rear chamber walls and the rotor before returning to the upper part of the roller gap. During the flow around the rotor, the material is subjected to shear and friction everywhere, causing the temperature of the rubber material to rise sharply and the viscosity to decrease, increasing the wettability of the rubber on the surface of the compounding agent and ensuring full contact between the rubber and the compounding agent surface. The clumps of the compounding agent, together with the rubber material, pass through the gaps between rotors, between rotors and upper and lower top bolts, and between rotors and the interior walls of the mixing chamber. They are sheared and broken, surrounded by stretched and deformed rubber, and stabilized in a broken state. At the same time, the convex edges on the rotor cause the rubber material to move along the axial direction of the rotor, playing a role in stirring and mixing, so that the mixing agent is evenly mixed in the rubber material. The compounding agent is repeatedly sheared and broken, causing the rubber material to undergo deformation and recovery. The continuous stirring of the rotor ribs ensures that the compounding agent is evenly dispersed in the rubber material and reaches a certain degree of dispersion. Due to the much greater shear force on the rubber material during mixing in the internal mixer compared to the open mixer, the rubber mixing temperature is higher, resulting in a significantly higher efficiency of rubber mixing in the internal mixer than in the open mixer.
